Proportion of Landslide 
Fig.13 Relationship between Band 6 CCT data 
and the proportion of landslide areas 
to total area in each watershed on daytime 
result, the landslide areas has constant ground 
temperature. Figures 13 and 14 establish above 
phenomena. 
6. CONCLUSIONS 
We have been conducted the procedure men- 
tioned above in the pilot area located north dis- 
trict of Noto Peninsula in the central district of 
Japan. These pilot areas are correspond to 2 
sheets of 1/25000 scale map.In this paper we ex- 
pand the pilot area to 6 sheets of 1/25000 scale 
map. On the expanded pilot area we got the new 
informations. For example , thermal band data 
for daytime and night time shows very interested 
results. These conclusions indicate that combin- 
ing thematic maps and satellite data using GIS 
techniques is successful estimating and zoning 
landslide areas.
